Common Electrical Calculations Explained

Calculating Current

I=PVI = \frac{P}{V}I=VP​

Where:

• $I$ = Current (A)

• $P$ = Power (W)

• $V$ = Voltage (V)

Calculating Voltage Drop

Vd=2×L×I×R1000V_d = \frac{2 \times L \times I \times R}{1000}Vd​=10002×L×I×R​

Where:

• $L$ = Length (m)

• $I$ = Current (A)
